' teams. (01. 19-139) This invention relates to spinning machinery, and is concerned primarily with the spinning of woolen fibres. Woolen fibres in an unsecured condition include a considerable amount of suint and natural grease, which render their spinning in such an unscoured condition an entirely impractical operation, so far as present-day spinning machinery is concerned, this being due to the fact that the grease from the unscoured wool 0 is taken up by the feed rolls over which the fibres are passed, and, in a very short'time, these feed rolls carry so much of this grease as to render their eificient operation impossible.

After wool has, been scoured and spun into yarn, some kind of artificial lubricants must be added to return the wool to a condition, at least, simulating that prior to scouring-r-otherwise, the resulting fabric will not have the desired properties.

Present-day spinning of Woolen fibres may, therefore, be characterized by the scouring of wool prior to spinning to remove suint and grease therefrom, and the subsequent addition of artificial lubricants thereto.

With the foregoing conditions in mind, this invention has in View, as its paramount objective, the provision of spinning machinery which is designed for the spinning of wool in an unsecured condition.

In attaining this end in a practical embodiment, present-day spinning machinery, including the usual feed rolls, is availed of, and this invention does not propose any material changes in the design of this machinery.

Accordingly, a more detailed objective in view is the provision of a so-called clearer which is designed for cooperation with the feed rolls of spinning machinery, and which is effective to clear grease or other foreign material which may be collected thereon, incident to passage of the unsecured woolen fibres thereover. Yet another object in view is the provision of a clearer device which is designed to be mounted on the framework of conventional spinning machines, and which device includes a clearer pad for each of the feed rolls of a spinning machine. Still another objective is the provision of a clearer device which includes a plurality of felt pads which are yieldably maintained in engagement with feed rolls of a spinning machine.

Other more detailed objects and advantages are associated with the carrying out of the above noted thoughts in a practical embodiment. These will in part become apparent and in part be hereinafter stated as the description of the invention proceeds.

The invention, therefore, comprises spinning machinery including a clearer device which consists of a plurality of felt pads yieldably maintained in engagement with the feed rolls of spinning machinery to keep the latter clear from grease and other foreign matter.

For a full and more complete understanding, thereof, reference may be had to the following description and accompanying drawings, where- Figure l is a side view, partly in section and partly in elevation, of certain parts of spinning machinery, with which this invention is concerned,

Figure 2 is a front View of a portion of spinning machinery with the present invention applied thereto, and

Figure 3 is an enlarged detail perspective showing of the clearer device per se.

Referring now to the drawings, wherein like reference characters denote corresponding parts, an angle bar consisting of part of the framework of spinning machinery, is shown in Figure 1 and referred to in its entirety by the reference character B. This angle bar includes a horizontal flange l0 and a vertically disposed flange H. A drive shaft is indicated at 2 and carried on the drive shaft are a plurality of feed rolls I3,

the cylindrical surfaces of which are grooved or ribbed, as indicated at M, to facilitate the driving action on the yarn. The drive shaft [2 which carries the feed rolls I3 is mounted and driven in a manner well-known in this art. Such mounting does not enter into the present invention, and it is not, therefore, herein illustrated and described.

Cooperating with each of the feed rolls I3 is a roller 15 which is provided with a proper surface for cooperating with the ridged surface M of its respective roll l3. Such a surface may be provided with a cylindrical casing N5 of cork or similar material which is carried by the roller l5. Each roller I5 is mounted on a'shaft I! which. is properly supported by the framework of the spinning machinery in a manner not herein illustrated.

A strand of woolen fibres which is to be spun into yarn is designated I 8, and is shown in Figure 1 as passing between the feed rolls I 3 and the rollers l5. From the feed rolls I3 the yarn l8 passes through an eye l9 formed in a wooden apron 2E3 which is hingedly mounted at 2| on a supporting member 22 that is secured to the ver-' tically extending flange H of the angle bar B, as by fastening members indicated at 23.

The above described mechanism is old and well-known in this art, and the clearer device provided by this invention is now described as including a wooden carrier member 24 which is disposed beneath the feed rolls l3 and which carries a plurality of felt pads 25, there being one pad 25 for each of the feed rolls l3.

As shown in Figures 1 and 3, the carrier member 24 has an upper surface thereof curved, as indicated at 26, so that this surface conforms to the feed rolls I3, the pads 25 being carried by the carrying member 24 on the curved surface 26 thereof also conforming to the curvature of the feed rolls !3. v

A spring supporting member designated 21 is shown secured at one end to the carrying member 24 by screw fasteners shown at 28. As many of the spring supporting members 21' may be employed as is found necessary to provide the desired supporting effects, but it has been found that for each carrying member 24 which carries six of the felt pads 25 two of the spring supporting members 21 provide satisfactory results,

The spring supporting member 21 is curved in the manner shown in Figures 1 and 3, and is anchored at 29 to a channel-fastening member 30 which is formed with a channel 3| that receives the horizontal flange H] of the angle bar B.

A set screw shown at 32 extends through the channel bar 30, and is effective to positively clamp the latter to the angle bar B. This set screw 32 may be formed with a wing operating member designated 33;

The clearer device is assembled with the remainder of the spinning machinery in the manner shown in the drawings, with the result that the felt pads 25 are yieldably urged into engagement with the feed rolls [3. As the latter rotate incident to feeding of the yarn l8, a certain amount of suint, grease or other foreign material will be transferred from the woolen fibres I8 to the respective feed rolls I3.

However, this foreign material is removed from the feed roll [3 by the felt pad 25 which is maintained in proper engagement therewith to provide the desired clearer effects.

While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be clearly understood that I am not to be limited to the exact construction illustrated and described because various modifications of these details may be provided in putting the invention into practice, within the purview of the appended claims.

I claim:-

'1. A clearer device of the character described comprising a carrier member having a curved scribed comprising framework including an angle 7 bar having a horizontal flange, a plurality of said rolls carried by a shaft which is mounted in the framework of the spinning machine, a clearer in engagement with the feed rolls, and spring M supporting devices for said carrier member having channel-receiving members at one end which receive the horizontal flange of the said angle bar.
